• cron_explainCron Explainread-only

  Explain a 5-field cron expression in plain English and flag mistakes. FREE. Typical input {"expression": "0 9 * * 1-5"} returns {"expression": "0 9 * * 1-5", "meaning": "at minute 0; at hour 9; every day of month; every month; day of week 1-5", "issues": ["none"]}; out-of-range fields are listed in "issues". Use to read a schedule back in plain English before trusting it. Assumes 5-field cron; not for 6-field or seconds-precision variants. Errors: on invalid, missing, or malformed input this tool never raises a protocol error; it returns {"error": "<what is wrong and how to fix it>"} (for ex…

• diff_textsDiff Textsread-only

  Produce a unified diff between two texts. FREE. Useful for comparing two SKILL.md versions. Typical input {"a": "<old text>", "b": "<new text>"} returns {"changed_lines": N, "diff": "--- \n+++ \n@@ ... @@\n-old line\n+new line"}; identical inputs return {"changed_lines": 0, "diff": "(identical)"}. The diff is capped at 400 lines. Use to show exactly what changed between two versions of a text. Not for judging the risk of a code change - the codereview server's review_diff does that. Errors: on invalid, missing, or malformed input this tool never raises a protocol error; it returns {"error": …

• json_validateJson Validateread-only

  Validate JSON text and summarize its structure. FREE. Typical input {"text": "{\"a\": [1, 2]}"} returns {"valid": true, "structure": {"a": ["array[2]", "int"]}}; invalid JSON returns {"valid": false, "error": "<parser message>", "line": N, "column": N} instead. Use when JSON may be malformed or its shape is unknown. Reports structure, not conformance to a schema. Not for testing a pattern (regex_test). Errors: on invalid, missing, or malformed input this tool never raises a protocol error; it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "text is empty — pass …

• lint_skillLint Skillread-only

  Lint one SKILL.md file the way marketplaces and agents parse it. FREE. Checks YAML frontmatter presence and required fields (name, description), description quality, body structure (procedure steps, rules, degradation), secret/credential leakage, injection-style phrasing, and size budget. Typical input {"content": "<full SKILL.md text>"} returns {"verdict": "pass" | "pass-with-warnings" | "fail", "errors": ["..."], "warnings": ["..."], "stats": {"body_words": N, "has_frontmatter": bool}}. Use on the full text of one SKILL.md. Not for the surrounding archive layout (packaging_check). Errors: …

• packaging_checkPackaging Checkread-only

  Validate a zip layout plan for a skill marketplace before packaging. FREE. Checks SKILL.md placement rules and flags junk files. Typical input {"file_paths": ["my-skill/SKILL.md", "my-skill/examples.md"], "marketplace": "agensi"} returns {"verdict": "pass" | "fail", "issues": ["..."], "skill_files_found": ["my-skill/SKILL.md"]}. Use on a planned file layout, before zipping. Not for the content of a skill file (lint_skill). Errors: on invalid, missing, or malformed input this tool never raises a protocol error; it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "…

• regex_testRegex Testread-only

  Test a regular expression against sample strings. FREE. Typical input {"pattern": "v(\\d+)", "samples": ["v12", "beta"]} returns {"pattern": ..., "results": [{"sample": "v12", "match": true, "matched_text": "v12", "groups": ["12"]}, {"sample": "beta", "match": false, ...}], "match_count": 1}. Use to confirm a pattern matches what you expect before shipping it. Not for validating JSON (json_validate). The pattern is compiled and run in a short-lived, CPU-capped child process, so a pattern that backtracks catastrophically is stopped instead of stalling the server. Errors: on invalid, missing, …
